本文研究了体外脉冲振动源在二维空间中的定位能力。我们测试了人类在用手检测脉冲振动源传播的振动波提供的时空振动触觉信息时，是否能识别脉冲振动源的方向或距离。具体来说，我们让用户以几种姿势把手放在硅橡胶片上。我们要求用户指出振动源的位置，当一个位置在片上被压痕。实验结果表明，尽管识别精度取决于手的姿态和振动源的位置，但在一定程度上可以识别出冲击振动源的方向。当手指与手掌接地并在中指周围设置振动源时，识别结果最佳，方向识别误差为6$^\circ$。相反，结果表明很难准确识别振动的距离。这项研究的结果提出了一种新的可能性，即在距离用户的手一定距离的地方嵌入振动触觉致动器。
This article investigated the localization ability of an impulse vibration source outside the body in two-dimensional space. We tested whether humans can recognize the direction or distance of an impulse vibration source when using their hand to detect spatiotemporal vibrotactile information provided by the propagated vibrational wave from the source. Specifically, we had users put their hands on a silicone rubber sheet in several postures. We asked users to indicate the position of the vibration source when a location on the sheet was indented. Experimental results suggested that the direction of the impact vibration source can be recognized to some extent, although recognition accuracy depends on hand posture and the position of the vibration source. The best results were achieved when the fingers and palm were grounded and a vibration source was presented around the middle fingertip, and the directional recognition error in this case was 6$^\circ$. In contrast, results suggest it is difficult to accurately recognize the distance of the vibration. The results of this study suggest a new possibility for directional display where vibrotactile actuators are embedded at a distance from the user's hand.
